Name: Stephen D. Winchell
Title: Presidential Innovation Fellow
Agency: Intelligence Advanced Research Projects Activity
Vulnerability sleuth. Winchell is detailed to the Intelligence Advanced Research Projects Activity, where he is helping to predict how emerging technologies could reshape the way the U.S. government conducts its intelligence operations. He created a tool for IARPA’s Trojans in Artificial Intelligence program that can help the agency identify vulnerability gaps in the deep neural network models used in AI solutions. His previous work with the Navy and Johns Hopkins University’s Applied Physics Lab has given Winchell insight into how adversaries might hack into intelligence systems and how to enhance IARPA’s ability to block those efforts.
